  • Patent number: 4240600
    Abstract: A kite-flying toy which can be lifted along a string from a player's hand to a position immediately before a kite hovering in the air, and which can be struck to a stopper provided just before the kite thereby to unlock a wing-holding means thereby to close the wings, so that the toy falls to the player's hand by its empty weight along the string. The toy comprises two frames, i.e., a vertical frame and a lateral frame, wherein the vertical frame is tilted or tiltable toward the player relative to the lateral frame so that the wings receive the wind pressure efficiently responsive to the angle of the string.
